Cannot connect to a router. Stuck at "Validating Identitiy"

[fsngnshiekfan]

When I try to connect to a specific password protected router with a specific computer it will not work properly. When I try to connect to the router(remember it's password protected) it attempts to connect, finds the connection, then says "Validating Identity, Firewalled" and stops at that process. It never asks for the password. The computer can connect to other wireless connections and the router works with other computers. Nothing abnormal is happening during the connection attempt.

I am attempting to fix this problem for a family member, and it will be a little harder then usual to get information, so if you need any more information please make a list.

OS: Windows XP

Check the setting for the NIC and the router. Make sure you are typing the password correctly.
make sure you are within range of the AP, Mic drivers installed, umm. yeah try it then. i have never had this problem before, I always make sure that the settings are correct of both sides.
